The Rock Krawler JL 3.5 Flex "No Limits" System was designed for those who want an easy bolt-in installation, minimal maintenance and the durability and off-road performance you expect from Rock Krawler Suspension. The X Factor Series adjustable lower control arms offer a total of 90 degrees of misalignment that drastically reduces the bind inherent in JL factory lowers. Rock Krawler’s industry leading triple rate coils give you 3.5 inches of lift to clear up to 40 inch tires, depending on model, and improve the on-road ride over the factory linear rate springs. All Rock Krawler JL systems include correction pads that reduce the spring bow inherent in the factory set up. The provided track bar geometry corrections, both front and rear, lets you perfectly center the axles so there is no compromise in on road handling.
